当用户单击名为 add New 的按钮时，将显示一个名为 AddNew 的弹出窗口。按钮本身具有称为 TRN 和 DOB 的字段数。我现在遇到的问题是，当用户尝试添加重复的 TRN 时，我试图显示错误消息，但不幸的是，只有在必填字段为空时才显示错误消息。

无论如何我可以在验证摘要中显示重复的错误消息，例如在必填字段中显示并在表单中保存所有先前输入的值。请指教。谢谢

这是我到目前为止的代码。谢谢

索引.cshtml

<input type="button" id="btnAddNew" style="height:50px; font-size:14px; width:95px; background-color:#3399FF; white-space: normal;" class="k-button" title="AddNew" value="Add New" />

<script type="text/javascript">

$(document).ready(function () {
    $('#btnAddNew').click(function () {
     window.open('@Url.Action("AddNew", "Details")', 'AddProduct', 'height=' + (window.screen.height - 450) + ',width=950,left=' + (window.screen.width - 5) + ',top=10,status=no,toolbar=no,resizable=yes,scrollbars=yes');
        });
});

</script>

如果我没记错的话，ValidationSummary 必须设置为 true 才能显示自定义错误。

编辑：要完整：

在您的 AddNew.cshtml 文件中，替换

@Html.ValidationSummary(false, "Please fix the following errors:", new Dictionary<string, object> { { "id", "valSumId" } });

和：

@Html.ValidationSummary(true, "Please fix the following errors:", new Dictionary<string, object> { { "id", "valSumId" } });
